The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for ...

But what have been the most significant physics prizes of the 21st century? I’m including 2000 as part of this century (ignoring pedants who say it didn’t start till 1 January 2001 ). During that time ...

IN ARIZONA, AT Kitt Peak National Observatory, a telescope has spent three years building a three-dimensional map of the heavens. In examining the light from tens of millions of galaxies, the Dark ...

How old is the universe—and how fast is it expanding? These are part of one of the biggest—and most contested—questions in science, and the answers could change our understanding of physics. In this ...
